STQP-MOTION FOR MUSIC=BOXES.

SPECIFICATION forming part of Letters Patent No. 395,440, dated January 1, 1889.

Application filed February 9, 1888. Serial No.263,i32. tNo model.)

To a whom it may concern.-

Be it known that I, GUs'rAvE J JACOARD,

of the city, county, and vState of New York,

have invented a new and Improved Stop-Motion for Music-Boxes, of which the following is a full, clear, and exact't'lescription.

My invention relates to the mechanism for stopping, starting, and governing musicboxes and the invention consists, principally, of a duplex stop acting upon the countershaft, so that there will be less strain and less wear upon the vertical shafts which carry the stop-arms.

The invention also consists of means for adjusting the vertical shafts, and also of an improved spring-brake to regulate the time of the music; and the invention finally consists of the construction, arrangement, and

combination of parts, all as hereinafter described and claimed.

Reference is to be hadto the accompanying drawings, forming apart of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a plan view of my new and improved stop-motion. Fi is a sectional plan view of the same, taken on the line a; of Fig. 3 is a vertical section on the line '3 y of Fig. 2. Fig. 4 is an inverted sectional view 011 line :2. .zr, Fig. 3, showing the brakedies. Fig. 5 is a detailed plan view of plates for adjusting the vertical shafts.

The support of the stop-motion in this instance is composed of the base-blocks A, formed with proj ctinparallel arms or plates A A, in which are journaled the shaft B and counter-shaft C. The shaft 1; is provided with the gear-wheel D and pinion E,which meshes with the gear-wheel. h of the main-spring barrel G. (Partly shown in Fig. 2.) The gearwheel I) meshes with the pinion II on the counter-shaft C for revolving the same. 011 said counter-shaft C secured the two gearwheels J J, which mesh with the wormsj on the vertical shafts K K, so that the motion of the shaft 0 will communicate very rapid motion to both of the said vertical shafts. shafts K are each provided with a stoparm, L, which arms revolve with the shafts, and which are adapted to be simultaneously engaged by the projections (Z (Z of the main stoplever M, pivoted atf to one of the side plates, 1 A. This stop-lever M is of the usual construction, except that it is provided with the 1 arm M, which reaches across the frame, and i is formed with two studs, (Z (I, to engage with two arms, L, instead of one, as in the common l construction, and it is acted upon in the usual l manner by the spring g, as shown in Figs. 1 i and 2. The upper ends of the shafts K are l provided with the frictioiebuttons h beneath the curved plate A in which the upper ends of said shafts are journaled, and against these buttons the curved springs X N are adapted to press, so as to act as brakes to the shafts K, and through them to the music-box. Tho pressure of the springs N upon the buttons 71 E may be diminished by pressing the springs N N away from the lnittons,whieh may be done in this instance by the fork t), journaled on the plate A and provh'led with a knob, m, above the said plate. The members 0 o of the fork span the springs N N, as shown clearly in l ig.l-. The rear ends of the springs are held in the plate Q, secured to the under surface of the plate A by t he screw 11, and the knob m is provided with a spring-arm, m, which rests on a notchetfl plate, 112*, secured to the top of the curved plate )0, so that said arm resting in the notches serves to hold the springs X at any desired position to exert the required pressure upon the buttons 71.

The lower end. of each of the vertical shafts K is journaled in an adjustiug- 'ilate, P, held 5 loosely in ntortises made in the blocks A A. 'lhese plates are each acted upon bva screw, l, for moving said plate in or out for carry ing the shaft K to or from the gear-wheel .I, thus serving to take up any wear and lost motion that may occur. The screws 1" work in scrtav-taps made in theback of the blocks A, and the head of each enters a notch, c, made in the adjacent edge of the plate P, as shown clearly in Fig. i, so that by turning the said screw the plate nnrvbemoved out or v in, as required. j Having thus described n1 v invention, what I claim as new, and desire to secure by Letters Patent, is

1. The hercin-described duplex stop motion for music-boxes, which consists of two vertical shafts having stop-arms, a stop-lever for each arm, and a counter-shaft provided with gears for revolving the vertical shafts, substantially as described.

2. The shafts K, provided with the brakebuttons 72, in combination with the springs N, arranged to press upon the buttons, and the button m and fork O, for regulating the springs, substantially as described.

The combination, with the shaft (1, of

the shafts K, the connecting-gear, and the adjusting-plates P, in which the lower ends of the shafts K are journaled, substantially as described.
